Filed: 1981-03-23
Abstract: PURPOSE:To compensate the temperature properties of an optical system, by providing a light transmission system which transmits the basic wave component to an optical transmission system and making use of the threshold voltage of a light emitting element plus the time of electric conduction of a photoreceptor. CONSTITUTION:Light emitting elements 2 and 3 emit the light with the output of a voltage or current transformer 1, and the optical output is transmitted to photoreceivers 14 and 15 via optical fibers 8 and 9. The electric signals received the photoelectric conversion through the detectors 14 and 15 are synthesized through a synthesizer 16 and then applied to an automatic gain controller and amplifier 17. On the other hand, the basic wave component extracted through a filter 21 is transmitted through a light emitting element 22, an optical fiber 25 and a photodetector 28 respectively. As the threshold voltage of the element 22 has no dependence of temperature, the maximum value of the input signal is obtained from the time width and the threshold voltage received at the detector 28. Then the gain of the amplifier 17 is controlled based on the above-mentioned maximum value of the input signal. Thus an output signal which does not depend on the temperature properties of a transmission system is obtained.
